React不会加载本地图像 [英] React won't load local images

问题描述

我正在构建一个小型反应应用程序，我的本地图像将无法加载。像placehold.it/200x200这样的图像加载。我想也许它可能是服务器的东西？ github 上的完整资源。

I am building a small react app and my local images won't load. Images like placehold.it/200x200 loads. I thought maybe it could be something with the server? The full source on github.

这是我的App.js

Here is my App.js

import React, { Component } from 'react';

class App extends Component {
    render() {
        return (
            <div className="home-container">
                <div className="home-content">
                    <div className="home-text">
                        <h1>foo</h1>
                    </div>
                    <div className="home-arrow">
                        <p className="arrow-text">
                            Vzdělání
                        </p>
                        <img src={"/images/resto.png"} />
                    </div>
                </div>
            </div>
        );
    }
}

export default App;

index.js：

import React, { Component } from 'react';
import { render } from 'react-dom';
import { Router, Route, Link } from 'react-router';
import { createHistory } from 'history';
import App from './components/app';

let history = createHistory();

render(
    <Router history={history} >
        <Route path="/" component={App} >
            <Route path="vzdelani" component="" />
            <Route path="znalosti" component="" />
            <Route path="prace" component="" />
            <Route path="kontakt" component="" />
        </Route>
        <Route path="*" component="" />
    </Router>,
    document.getElementById('app')
);

和server.js：

and server.js:

var path = require('path');
var express = require('express');
var webpack = require('webpack');
var config = require('./webpack.config.dev');

var app = express();
var compiler = webpack(config);

app.use(require('webpack-dev-middleware')(compiler, {
  noInfo: true,
  publicPath: config.output.publicPath
}));

app.use(require('webpack-hot-middleware')(compiler));

app.get('*', function(req, res) {
  res.sendFile(path.join(__dirname, 'index.html'));
});

app.listen(3000, 'localhost', function(err) {
  if (err) {
    console.log(err);
    return;
  }

  console.log('Listening at http://localhost:3000');
});

推荐答案

使用Webpack时，您需要需要图像以便Webpack处理它们，这可以解释为什么外部图像加载而内部不加载，所以而不是< img src = {/ images / resto .png} /> 您需要使用< img src = {require（'/ images / image-name.png'）} /> 将image-name.png替换为每个图像的正确图像名称。这样Webpack就能够处理和替换源img。

When using Webpack you need to require images in order for Webpack to process them, which would explain why external images load while internal do not, so instead of <img src={"/images/resto.png"} /> you need to use <img src={require('/images/image-name.png')} /> replacing image-name.png with the correct image name for each of them. That way Webpack is able to process and replace the source img.
